The effect of firearms is really good

More unique characters and enemies may make the game more fun to play.

Good job!

Tight movement controls, relatively forgiving hitboxes, and some great sfx! Overall a fun roguelike experience.

The only thing i would suggest is to add a power scaling element. Every survival roguelike needs one. More guns, powerups, damage boosters, anything really. The challenge of enemies scaling beyond your ability can still be present, but the player needs to grow as well.

Your game is really good I got a 406 score >;)
